`Application filed Aprn 29, 1914. serial No. 835,185.

To all whom it may concern:

Beit known that I, GUNDER P. SMAAGAARD, a"citizen of theUnited States,residing at Cerrogordo, in the county of Lac qui Parle and State ofMinnesota, have invented certain new and useful Improvements in Neck-Yokes; and I do hereby declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention hasfor its object to provide an improved neck yoke, and, tothis end, it consists of the novel devices and combinations of deviceshereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like `parts throughout the several l views.

- parts being broken away; and Fig. 3 is a view showing the vehicle polein side elevation and the improved neck yoke applied thereto, intransverse section.

The numeral 1 indicatesA a vehicle pole having the customary metallicpole cap 2,.

with a stop lug 3.

Referring now to the improved neck yoke,

t the numeral 4 indicates a pair of axially alined tubes, spaced apart,at their inner ends. As shown, these tubes 4 are formed from sheetmetal, with their longitudinal edges turned outward, to afford dependingflanges which are securedA together by rivets; or, if desired, theselongitudinal edges may be welded. Telescoped into the outer end of eachtube4 is a reinforcing sleeve 5. Collar strap loops 6 are secured, oneto each end of the neck yoke. These loops,\as shown are in the form ofU-shaped bolts, with their prongs passed transversely through the tubes4 and sleeves 5, and are secured in position by nuts havingscrew-threaded en gagement therewith.

Interposed between the spacedinner ends end, upper and lower segmentallugs 9. The inner end portions of the tubes 4 are connected by upper andlower channel straps 10, rigidly secured thereto, as shown, bynut-equipped bolts. These straps 10, at their intermediate portions, areoutwardly and transversely bulged, at 12, to receive and holdtherebetween the pole socket 7. The head 8 of the pole socket 7 works onsegmental surfaces 13 formed on the` outer longitudinal edges of thestraps 10, and the segmental lugs 9 work in segmental notches 14 formedin the rear longitudinal edges of said straps. The straps 10, at thesegmental notches 14, are, as shown, preferably eX- panded, to affordrelatively wide wearing surfaces, on which the lugs 9 work. Obviously,the head 8 and lugs 9 prevent endwise removal of the pole socket fromtheneck yoke, but permit a limited swinging movement of the pole socketlongitudinally of the neck yoke. These elements also permit a limitedrotary movement of the pole socket, with respect to the neck yoke.

Integrally formed with the lower lug 9 is a clip 15, adapted tointerlock with the lug 3 on the pole cap 2, by substantially a quarterturn of the neck yoke in respect to the pole. This clip, wheninterlocked with the lug 3, Vholds the neck yoke against longitudinalsliding movement on the pole cap 2, but permits a free rotary movementin respect thereto.

What I claim is:

1. A neck yoke comprising a pair of axially alined tubes, a pole sockethaving at its rear end portion segmental lugs, said pole socket beinginterposed between the inner ends of said tubes, and upper and lowerchannel straps connecting said tubes and embracing said pole socket,said straps having in their inner longitudinal edges segmental notchesin which said lugs work.

2. A neck yoke comprising a pair of axially alined tubes, a pole socket,having at its forward end a head, and having at its other end upper andlower segmental lugs, said pole socket being interposed between theinner ends of said tubes, and upper and lower channel straps embracingand rigidly secured to the inner end portions of said tubes, said strapsbeing transversely bulged outward to receive' said pole socket betweenits head and segmental lugs, to hold the same against removal from saidstraps, said straps having in their inner longitudinal edges segmentalnotches in which the Segmental lugs of said pole socket Work.

3. A neckyoke comprising a 'pair of axially alined body members, a polesocket,-

havng, at its rear end portion, segmental lugs, said pole socket beinginterposed be- Y tween the inner ends of said body members,v and upperand lower straps connecting said body members, and embracing said polesocket, said straps having, at `their inner 10 'Copies f this paten'tmaybe obtained for ve centsk ea'ch, by'addressin'g the CommissionerffPaktents, Washington, DfC.
